How come Nog had to go to a Starbase for a new leg? Bashir gave Bareil an artificial brain not so long ago. He can manage a new brain but not a new leg?

And following on from "Time's Orphan", how come Molly could only get a few hours in the holodeck even though her removal caused serious mental trauma, but Nog can spend as long as he likes in there just because he's in a sulk?

Also, in this episode they claim that Bashir created the Secret Agent, Battle of Britain and Viking holoprograms. In fact, "Bar Association" shows that the Viking program was created by O'Brien rather than Bashir.

Plotline

After loosing his leg on AR-558 two episodes ago, Nog returns to a heroes welcome on Deep Space Nine. But he finds that he cannot face the reality of his injury, preferring instead to hide out in Vic Fontaines holographic bar.
